The best approach to develop pipelines in ZOHO.CRM is to create them in your language and then assign reference values (names) in english. It will give you a possibility to keep several language instances of your pipelines. Remember, that it's good to store information once and then reuse. So, while creating blueprints in your ZOHO CRM instance, don't create multiple records (pipeline stage names or blueprints). Do it once and then translate.

Step 1: Change your language to your language

Creating pipelines and naming your pipeline stages must start with creating all you need in english. So, go to your zoho account page and set your language to your language. 

Step 2: Create your pipeline in your language

Step 3: Translate into other language

Once you have your pipeline created, you have to set up reference values in english. Reference value is a system-defined name, which is used in API, or in our case - for translation. You actually created your foreign-language names and point them to an english-based value. You can point multiple foreign language names to one english-sounding value.

That's all!
Once you change your account-locale into english, you will see reference values you've added:
